What is the structure of a stroma?
What is the structure of a stroma?
Stroma is made of an outer membrane and a complex network of inner membranes that goes on to form the grana – disc like structures arranged in a stack. Membranous extensions connect various grana together.
What is the stroma What is its function?
Stroma: The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water. Thylakoid: A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.
What is called stroma?
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma. Photosynthesis occurs in two stages.
Where is stroma located?
the chloroplast
The stroma is located in the chloroplast of a plant cell.
Is stroma and stomata the same?
What is the difference between Stroma and Stoma? A stoma is a microscopic pore surrounded by two specialized guard cells found in the leaves and stems. Its main function is gaseous exchange. The site of the light independent reactions of photosynthesis is the stroma.
What is the difference between stroma and matrix?
Dear student,Matrix is any space which is viscous because of special functional materials it contains. But Stroma is the material present inside the chloroplast and forms the floor of it in which all substances of chloroplast are present like cytoplasm of the cell.
Why are leaves green?
The green coloration in the leaves of most plants is due to the presence of chlorophyll, a pigment used to absorb energy from the sun.
What is the difference between Grana and stroma?
Grana and stroma are two structures of chloroplast. Chloroplast is the organ where reactions of photosynthesis take place. The main difference between grana and stroma is that grana are the disk-like plates embedded in the stroma whereas stroma is the homogeneous, jell-like matrix of the chloroplast.
What is the meaning of the name stroma?
Stroma: Stroma refers to a colorless jell-like matrix of chloroplast in which the dark reaction of photosynthesis takes place. Grana: Grana are the disk-like plates in the stroma. Stroma: Stroma is the jell-like matrix of the chloroplast.
What is Stroma in chloroplast?
Stroma refers to a colorless jell-like matrix of the chloroplast in which the dark reaction of photosynthesis takes place. Enzymes required for the dark reaction are embedded in the stroma. Stroma surrounds the grana.
What is the function of the stroma in mitochondria?
The stroma is the site of carbon dioxide fixation and where the synthesis of sugar, starch, fatty acids, and some proteins occurs. While the inner membranes of mitochondria have many folds called cristae to increase the surface area, the inner membranes of chloroplasts are smooth.
